Allbirds Review, Is Allbirds Non-Toxic?
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
Across 3 graded products, Allbirds averages Good (65/100). On disclosure, the brand says nothing publicly about PFAS. None of its products grade Good or better yet. Grades are model-based estimates, not lab results.

organic cotton blend, no water-repellent coating disclosed
Lower concern, natural materials with no known water-repellent coating treatment, but no explicit PFAS commitment from brand.
⚠Risky category by default
Allbirds
Women's Intimates & Sleepwear Allbirds Trino Bralette
Merino wool, recycled materials (Allbirds typical blend)
Lower-concern base materials, but brand silence on PFAS processing leaves a data gap.
⚠Risky category by default
Allbirds
Anytime Bralette Light Grey Xs
Organic cotton blend with TENCEL lyocell
